Compound for preserving wood



To all whom it may concern: 4 Be itknown that 1, WILLIAM A'RMISTEAD GAYLE, a citizen of the-United States, residing at Montgomery, in the county of Mont- 5 gomery-and State of Alabama, have invented a newand useful Composition of Matter for Preserving Vegetable Fiber, of which the following is a clear, full, and exact description. v I mix together about equal parts of comro mon ground ocher, and crude cotton-seed oil, while at about the same temperature as the atmosphere, thus producing a liquid about the consistency of good house-paint. To this liquid may be added withadvantage about U '15 one-sixteenth of its weight, in common resin. The compound should be gently heated, be-

ing well stirred during the heating process as the heating is only for the purpose of liquefying the resin.- 1 -20' This composition is bestapplied to articles made of vegetable fiber by immersing them in it. Bags and similar-articles should first be turned wrongside out, and then be immersed. ;Any excess or surplus liquid should be re- -z 5 moved from the bags by wringing.

.7 The composition of matter may be employed for the protection of wood submerged in either fresh or salt water by immersing the wood in j the composition, or applying the composition 0 with an ordinary paint bt ush. .By treating vegetable fiberwithtlii s compoundeach fiber .r' *becomes thoroughly coated, thereby render 5 ing it impervious to the action of water, air and acid.

SPECIFICATION forming part of Letters Patent 1Y0. 497,471, dated May 16, 1893.

h Applicationfiled June 28,1892. Serial No.438,244. (Nospecimens) is produced by thegrease in tralizing the acid which comes in actual contact with the fiber, so coated by the fluid; the

known afiinity of acid for water, induces the V,

acid to penetrate any fiber which has ab- YW L M Y I TEAD GAYLE, 0F MONTGOMEREALABAMA] thefluid, neu- 'sorbed water, either from contact with the damp ground, or rain to which the articles may have been exposed. Wood is preserved by this composition,as the wood coated with 45,

fluid is thoroughlyinsulated and thereby protected from the action of salt or fresh water, as well as from the action of the air. The

resin gives greater body and adhesiveness to l the fluid, and further renders the wood thus coated most distasteful to destructive insects, and prevents them attaching themselves to the woodand from destroying it. e V

I am aware that it is not new to incorporate ocher with vegetable oils, including cotton seed oil, but this mixture without the resin wood, such as piles, &c., needs this addition to thoroughly keep it from attack by d e- Y structive insects.

Having thus described my invention, what l'claim as new, and desire to secure by Letters Patent, is-

The composition of matter for vegetable fiber consisting otlgn substantially the proportions stated.
